Moog: Actuator for Customized, Critical Service

Spectork Valve Moog smallMoog Inc. has released its Moog Spec-Tork custom pneumatic and hydraulic rotary actuators to meet OEM torque and speed specifications. Spec-Tork actuators satisfy special customer requirements that vary from the capabilities of Moog’s standard actuators. For example, the Spec-Tork can meet applications that might include: rotations of less than 90°; special cushions for high speed requirements, electro-hydraulic actuators and systems, integral valving and special mounting flanges. Moog’s engineers can also customize its Spec-Tork actuators for applications including lift and turn, dampers, and fluid power service.

The Spec-Tork can provide millions of cycles of continuous service and achieve 90-degree rotation in less than five seconds, for catalytic cracking units, pipe line valves, and electric valve actuation and R&P valve actuation in processing plants. For natural gas processing plants, the fireproof-enclosed Spec-Tork can produce 1,440,000 pound-inches of torque and have a hydraulic pressure rating of 3,000 psi. The Spec-Tork’s end-of-stroke design reduces the shock to both the actuator and the valve it controls, which extends service life.
